Provides support for the search pane in apps that participate in the Search contract. The search pane opens when users activate the Search charm and provides a consistent, touch-friendly search box and optional search suggestions.

An app can't use both the search box (Windows.UI.Xaml.Controls.SearchBox for XAMLUniversal Windows Platform (UWP) app, WinJS.UI.SearchBox for HTMLUniversal Windows Platform (UWP) app) and the SearchPane. Using both the search box and the search pane in the same app causes the app to throw an exception with this message: "Cannot create instance of type 'Windows.UI.Xaml.Controls.SearchBox.'"

Enables the app to signal when it has finished populating a searchSuggestionCollection object while handling the suggestionsrequested event. Apps should use a deferral if and only if they need to respond to a request for suggestions asynchronously.
